# WEILINKCRANE
> WEILINKCRANE (weilinkcranes.com) is a Chinese manufacturer of overhead crane, gantry crane and hoisting-system components rather than complete cranes: forged crane hooks and hook blocks from 5 t to 500 t (DIN 15401/15402 single and double hook blanks, FEM 2m European-type blocks, motorized rotating and fully enclosed ultra-heavy blocks, laminated plate hooks), crane sheaves and pulleys (hot rolled, integral forged, ring forged, double-web welded hollow), forged crane wheel and traveling wheel assemblies, wire rope drums and hoisting winches, European-type, metallurgical, explosion-proof and water-gate electric wire rope hoists, jib cranes, clamshell/orange-peel grab buckets, spreader beams, slab lifting clamps, coil lifting hooks, turning lifting devices and pulley blocks. Products are custom-built to customer drawings and serve steel mills, ports, shipyards, foundries, precast plants, power stations, wind-power and waste-handling facilities, supported by an engineering blog covering material selection, heat treatment, FEA, ultrasonic testing and maintenance practices.

Product pages are organized by category with numbered suffixes (e.g. Crane-Hook-1.html … Crane-Hook-26.html); several pages in a series share near-identical body copy, so the distinguishing information is in the page title or H1 (tonnage, sheave count, hook configuration). Nearly every product is customizable by drawing, load capacity, temperature duty and material grade, and standard references used throughout are DIN 15401/DIN 15402 (hook blanks), FEM 2m (working class) and 35CrMo / DG20Mn / 30Cr2Ni2Mo forging materials. Blog articles live under both top-level slugs and /news/ numeric URLs; the /news/(.*?).html items and the top-level *.html items are the same knowledge-base. Contact and company details are only on the two /site-page/ URLs, and the site has no public pricing — inquiries go through the Contact form.
